Signature

def trim ( self , tol = 0 )

Summary

Remove trailing coefficients

Extended Summary

Remove trailing coefficients until a coefficient is reached whose absolute value greater than tol or the beginning of the series is reached. If all the coefficients would be removed the series is set to [0]. A new series instance is returned with the new coefficients. The current instance remains unchanged.

Parameters

tol : non-negative number.: All trailing coefficients less than tol will be removed.

Returns

new_series : series: New instance of series with trimmed coefficients.
